I purchased a robot vacuum from them for $350. After 4 months of normal use, it began giving an error and would not work. It was within the 1-year warranty for free repair. I followed their instructions for returning it exactly as they said. I paid $100 to send it back. They said they couldn't receive it past customs, although I sent it EXACTLY as they told me too. And since it was past 45 days after purchase, they would not refund my money. Bottom line, there is no way to get the product back to them for repair, and they will not honor refunding it! I feel completely victimized. I have thrown away $450 purchasing from them a product that died and then paying to ship it back - which does not work!!! (I wonder if they knew that it wouldn't?!) Please, please, please do not purchase anything from them!!! So worth the extra money to purchase within the United States where people are under our laws and we know we can mail to them!!!
